9.2 Output Calibration
Introduction
The UDA2182 is available with two standard and one optional analog outputs. The
output signals can be adjusted to trim the high and low output current or voltage values
over a range of ± 0.4 % of span to compensate for component tolerance variations.

Required equipment
Output calibration involves connecting a meter to the Analyzer’s output terminals.
The meter required for output calibration depends on the type of outputs.
• Current outputs: current meter capable of resolving 0.01 mA over the range 0 to 20
mA dc
• Voltage outputs: a 250 ohm ± 0.05 % shunt and a volt meter (capable of measuring 1
to 5 Vdc within 1 mV)
A screwdriver to fit the terminal block screws and the screw securing the terminal board
retainer is also required.
Procedure
To calibrate outputs, follow the procedure described in Table 9-1 Procedure for
Calibrating Analyzer Outputs. The output terminals are inside the case as shown in
Figures 6-1 through 6-6.
